DEVELOPMENT OF PLUG-IN HYBRID ELECTRIC LIGHTAND MEDIUM-DUTY COMMERCIAL VEHICLES

摘要

The Electric Power Research Institute (EPRI) is currently conducting a long-term project to promote the development of grid-connected, plug-in hybrid electric vehicles (PHEVs) for the commercial automotive market. This collaborative effort with partners in electric utilities, the automotive industry and government includes subtasks of specification development, prototype vehicle design and construction, and PHEV demonstration programs. The preliminary powertrain configuration and battery specifications are discussed and three schemes for energy management are introduced. Simulations of the fuel consumption of a PHEV delivery van are performed and the results are translated into fleet-based results using a mileage weighted probability factor. This analysis allows comparison of the relative fuel consumption of the proposed vehicle energy management strategies.
